Homogeneous Systems of Linear Equations - Trivial and Nontrivial Solutions, Part 1. In this nine-minute video, Mr. Patrick shows what a homogeneous system of linear equations is, and shows what it means to have only trivial solutions. In the next video, the instructor works out an example that has non-trivial solutions.

This program shows how a theoretical understanding of the driving force for chemical systems can lead to further development of new technologies and to the discovery of new phenomena, in practice. In teaching, this is done through the creation of a close relationship between the science and mathematics of chemical processes, through problem-solving activities. These activities, which are based on a systematic interpretation of chemistry into mathematics, make the connection between theory and practice. These basic skills form the foundation for learning about chemical systems.

The development of measuring systems is a great human accomplishment. The early Egyptians created a unit of length, the cubit, based on the human forearm. The English and others, used the human foot and grains of barley corn to measure length. The metric system started with an fascinating attempt to define the meter using time. The meter evolved through a number of incarnations many involving distances taken from the planet. Today the meter is defined using the speed of light. This definition relies on a reliable means for measuring time. Time and space have been joined in our current definition of the meter. (07:23)

Mrs. Matthews science class has been studying the organs and systems in the human body. They have built on their studies over the past two weeks from smallest to largest: organelles, cells, tissues, organs, systems, and organisms. This weeks six centers included (1) A.R. books read with partners (2) crossword puzzle that included definitions of organs and systems (3) flashcards with pictures of various key organs in the body (4) two web sites using multiple choice quiz/game formats (5) magnetic matching game and (6) the "Can-Do" game from Lakeshore. Students also completed two extensive art activities this week. Students drew cells all over a Kleenex tissue and then glued the tissues onto organs to remind them of the progression from smallest to largest. (04:24)

How did people begin to understand themselves in relation to the natural world and to the unseen realms beyond, and how was religion a community experience? In this unit, animism and shamanism in Shinto are contrasted with philosophical and ethical systems in early Greece and China, and the beginnings of Zoroastrianism, Hinduism, and Judaism. (28:35)

In this interactive activity from Kinetic City, Arnold is missing all of his organ systems. The organs of the human body are critical for maintaining conditions that are necessary for life, and must operate in concert with each other to do their jobs. Help Arnold identify these important organ systems and put them back into his body where they belong.
This interactive quiz game times the student as they try to put the different systems of the body together again. As you move the cursor over the body part, it gives you a brief description of the organ
